PHOTOGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 395,899, dated January8, 1889. Application filed June 19, 1888. Serial No. 277,507. (No model)To all whom it may 0011 ('PI'U:

Xew York city, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Photographic (:ameras,ot which the following is a specification.

My invention relates to improvements in photographic cameras, parts ofthe invention being applicable to detective cameras only and parts beingadapted to cameras for long exposures, as well as detectivecameras.

The invention consists, tirst, in the const ruction and arrangement ofparts whereby the 1 camera may be convenientlyheld in the hand and aimeiso to speak, at the object to be i with a door, t, through which thefocusing Be it known that I, SYDNEY l. IIASEY, a citizen of the UnitedStates, and a resident of t can be taken, as usual.

D is a door supported and moving on the arms E, which may be swungdownwardly and away from the camera-box for the insertion of theplate-holder.

F is the usual rack andpiniou, operated by thumb-screws G, for securingthe focus.

photographed, whether in motion or not, and

so that the camera may follow the object, if in motion, and be focusedmeantime, and when the proper focus is obtained and the object .1

properly centered in the lens, then, by operating-a triggerdike device,the sensitive plate will be instantly located in front of thegroundglass plate, also the instantaneous shutter will be turned fromlight to dark during the movement of the sensitive plate to its positionin front of the ground-glass plate, and then the shutter will beflashed, making the exposure, and again instantly turned to dark and remain then at rest.

The invention consists, second, in a tilting lens-holding frame, wherebythe object may be brought more easily into the field.

In the drawings the same reference-letters indicate the same parts inall the figures.

Figure 1 is an elevation of my camera, all the parts being in position.Fig. 2 is a longitudinal vertical section of my camera on the line :0 aof Fig. 1. Fig. 3 is a crosswise vertical section of the camera on theline y y of Fig. 1. Fig. l is a front view of the tilting lens-holdingframe. Fig. 5 is a view of the under side of the camera, showing thetrigger. Fig. 6 is a sectional view of the interior of the camera,showing the stop forthe shutter and the devices whereby it is operated.

A is a camera-box, made of such material as may be desired. with aconvenien tly-located handle, A, whereby it may be firmly held.

B is a movable end piece, as usual, provided it is an outer frame orsupport; for the inner lens-supporting frame, t).

I is the bellows.

J is the usual flash-shutter, operated by the tsn-in K. or in any otherdesired manner pivoted at L, and provided with the usual opening, M,which may be of such shape and precise location as preferred.

All the above-recited parts of the pparatus are or may be the same asthose nowgenerally in use.

deferring to the interior of the camera, as especially illustrated inFigs. 3, 3, and t3, Xis the ground-glass-holding frame. It is mounted ona slide, which is supported on suitable ways and slide-strips, l 1, (seeFig. 3,) in the bottom of the camera-box.

Q (see Figs. 2 and 3) is a spring fastened at the forward end of thecamera-box, the free end of which presses against the front end of theslide 0 and normally tends to push it and the ground-glass framerearwardly.

R is a catch which is fastened to the slide 0, the end S of which passesdownwardly through the bottom of the camera-box in abayonet-slot joint,'1. (Shown in Fig. 5.) The end S of this catch has a slight lateralmovement to enable it to pass into the bayonet part of this slot, and istherefore attached to the slide 0 by a single pivot, as shown.

U is a trigger pivoted to the under side of the camera in such positionthat itmaybe easily reached by the fingers operating thev front wall ofthe camera-box and enters the hole \Y in the shield. This hole isrepresented as being directly under the opening of the shutter; but it,and also the holding device Y, may be located at any other ')referrcdplace. The holding device of course moves rearwardly with the slide 0.

X are supports for the sensitive plate holder. They are pivoted at Y tothe sides of the camera-box, and are supported at their other ends bythe upper edge of the grtjiund- 1 glass-holding frame when that frameforward position; butthey are released and drop when the frame is in itsrearmost position.

Z is the plate-holder. It consists of a backed outer frame or ease, (I,provided with forwardly-extending flanges b on all sides to secure alight-tight connection with the hinged cover-like part c, which holdsthe pl ate (1. This cover-like part. (.1 may be hinged by an ordinaryleather or canvas or other preferred hinge, preferably at c, to one sideof the ease u, and the plate a is slid into it from the top when open,and there is a lip-shaped flange, f, on three sides of the cover-likepart,whereby the plate is held in position. The plate is of courseinserted inthis holder in the dark room, and the cover-like part is thenfolded over and snugly pressed into the case a. The flanges on theseveral parts completely exclude light.

Referring now to Figs. 3 and U, y is alcver pivoted at It and providedwith a forwardlyprojec ting stud, i, which is so located and adjustedrelative to the flash-shutter J that a tangentially-extending pro jeetion, j, made on the side of the shutter will strike against this stud1' during the revolution of the shutter. At thelower end of the lever ga laterally-c tending pin, It, enters a slotted plate, 7, on the end ofa pivoted arm, in, (see Fig. 6,) which extends to the rear part ofthecamera, the under side of which, at its rear part, is cut away, so thatit may lie snugly down on the bottom of the camera.

12 is a small spring, which normally retracts the lever n, compellingits forward end to occupy a position near the bottom of the camera. Thisforward end of the lever may also, as shown, he made much heavier thanthe rear end, so that gravity, also, will tend to bring it down.

Referring now to Figs. 1 and l, in these figures I illustrate thetilting-lens-holding frame.

IT, as before stated, is a frame which is attached to the rack-bar.

0 is an inner frame, which slides in the groove 19 in the insideuprights of the outer frame, H.

q is a set-screw which, in a manner well known, passes through the outerframe, ll, and presses against a plate on the edge of the inner frame,0, whereby that frame is held in any desired vertical position.

7* is the lens-holding plate or frame. It is pivoted centrally oreccentrically, as at s, to the frame o. It is shown as pivotedeccentrically in Fig. 4-. '1 is a set-screw, similar to the set-screw1', which passes through a projeeting portion of the frame 0 and engageswith a plate on the lens plate or frame r. By this means it is apparentthe lens-holding plate or frame may be tilted and fastened by theset-screw as may be desired.

The operation is as follows: The door (Z is swung downwardly to exposethe opening in the rear of the camera. The camera is then turned bottomside up, whereby the lens-holding plate-supports X drop to the upperside of the camera-box, and while in this position the grouml-glassframe is pushed forward and the end of the catch S is locked into thelmyonet-joint part of the slot T. The camera is then turned over again,right sidenp. The plate-holder Z is then pushed into the camera throughthe opening left by the removal of the door l), the cover e of theplate-holder being on its under side, and the door is then again closed.The shutter J is then adjusted in any suitable mannersuch as by a leverextending through the side of the camera-box (not shown) or in any otherpreferred manner, many such devices being now well known, so that theholding device V will enter the hole \V in the under side of theshutter. The opening .\l in the shutter will then of course be in linewith the lens. The door C in the rear wall, ll, of the camera is thenopened, and the entire instrument being held by the handle A in onehand, or otherwise supported, it is focused by the operator in the usualmanner. \Vhen he finds the object properly focused and centered,hecloses the door (3 and moves the trigger l in the direction of the arrowwith his fingers. (See Fig. (This trigger, it will be noticed, is solocated that the third and fourth fingers of the hand which is operatingthe left-hand thumb screw may conveniently reach it. Thus no removal ofthe hand from the thumbscrew to operate the trigger is necessary; but,on the contranv, the trigger may be operated the instant the object isfound to be in focus and properly centered.) The trigger forces the endS of the catch R out. from thebayonet part of the slot. into thestraight part. The spring Q then at once pushes the ground-glass platerearwardly. This withdraws the holding device from the shutter J. Theshutter then, actuated by its spring, rotates to the left (see until theprojection j strikes against the stud i on the pivoted lever g. Theshutter is then arrested for an instant. ing that instant theground-glass frame a has traveled still farther rearwardly and hasreleased the free ends of the plate-supports X. The instant this takesplace the supports drop, swinging forwardly, and rest against thecushions a, (see Figs. 2 and 3,) which are attached to the sides of thecamera-box. The

plate-holding cover-like part 0 (see Fig. 2) then instantly drops,swinging downwardly D ur- IIO into the position previously occupied bythe ground-glass plate. lts arc is shown in Fig. U in the dotted lines.As it nears its lowermost position, it. strikes the rear end of thelever m, depressing it and throwing its front end sharply upward,stretching the spring 12. The slotted plate I on the forward end of thelever m, acting on the pin 75, then throws the lower end of the lever gto the left. (See Fig. 3.) This carries the stud '2' so far to the leftthat the projection j on the edge of the shut ter is disengaged from it,and the shutter then makes an entire ievolution, exposing the plate tothe action of. the light; but be fore the shutter has had time to makeits complete revolution the plate has passed be yond the end of thelever m, and the spring n has retracted the forward end of the lever, sothat the plate is held in its position by the rear end of the lever,which passes up in front of it, and also the pivoted lever g has beenbrought back again to its original position by the action of the pin 7;in the slot of the plate I, and, this oecurrin g before the shutter hashad time to make its complete revolution, the projectionj comes again incontact with thestud and the shutter rests in that position dark. Theapparatus bein returned then to its original position and a new platesupplied to the plate-lmlder, the apparatus is ready fora second use.

It will be seen that my improved plate holdernvhich may be made ofleather or pasteboard, if preferred, although it may also be constructedofmore durable material, is exceedingly light and compact, and is inthose respects,l believe, superior to plateholders ordinarily made, andalso that by reason of the tilting of the lens-holding plate or frame anobject which under certain circumstances cannot be very well focused maybe obtained, although, perhaps, not exactly centered on the groundglass. Nevertheless under certain circumstances this vertical adjustmentand tilting of the lens-tube will be found very advantageous.

I do not limit myself to the details of construction described andshown, since it will be apparent to those who are familiar with this artthat many alterations may be made therein and still my invention beemployed.
